The dealer was incapable of installing the JBL system at time of purchase.......so they contract after market systems added to the new vehicle sale to third party audio stores.
I did email Toyota, but as I said prior......I'm beginning to see that it would be a waste of my time (and most likley my money) to chase the JBL issue. I'll probably just hit up Amazon or Ebay after I narrow down what I want.
Wiring from the head unit to the amp is stupid simple. There's only two or three wires IIRC, its all digital. The only pain in the butt you'd have is wiring the amp up for power and to the speakers. If this sounds acceptable to you, then I will be back in Cape Cod in november and I will package up what I have there. I will throw you a good deal, seeing as I'm not doing anything with the gear, its just collecting dust.
